COMBINED WINDOW LOCK AND VENTILATOR.

Specification of Letters Patent.

Patented Dec. 10, 1912.

Application filed April 10, 1912. Serial No. 689,773.

To all whom it may concern:

Be it known that I, JAMES E. MILL-En, a citizen of the United States, residing at Braddock, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Combined V'Vindow Locks and 1ventilato-rs, vof which the following` is a specification.

My invention relates to that particular class of window locks in which the windowcasing and one of the sashes is provided,y

vices are such that they cannot be tampered` with or unfastened from the outer side of the window when the sashes are closed or either one slightly open for the purpose of Ventilating the room.

A. further object of my invention is to provide a form of locking device in which the holes in the plates are in such position with relation to the spring-catch as to pro-` vide an automatic engagement when either sash is opened to a certain extent, but permit free movement of the lower sash be-. yond that point and the locking of the same by operation of the catch. Other objects and advantages of the invention will hereinafter appear, and what I claim as new, and desire to secure by Let-v ters-Patent is more specically set forth in the appended claims. In the accompanying drawings, which form a part of this specification: Figure 1 is an elevation, looking at the inner side of a window provided with a combined lock and ventilator device constructed in accordance with my invention. Fig. 2 is a trans-- the plates which are attached to the window* casing and upper sash, respectively. Figs. 6 and 7 are end views of said plates.

Like numerals of reference indicate like parts in all the figures of the drawings.

My invention is applied to a window of conventional form, comprising a casing or frame 8, upper and lower sashes 9 and 10, respectively, which slide in said casing or frame, a parting bead 11, between the sashes, and inner and outer' beads 12 and 13, respectively, forming guides for the sashes; the ends of the upper rail 1()a of the lower sash and lower rail 9a of the upper sash being cut away at their meeting edges, as usual, to receive the parting-bead 11, as shown in the drawings.

My improved devices for locking the sashes closed, as well as locking either one or both partly open, are located at one side of the window, being attached to the part-V ing-bead and to the sashes, as hereinafter particularly described.

14 designates a metal strip or narrow plate having an outwardly-projecting fiange 14a at one of its longitudinal edges by which it is nailed or otherwise attached to the parting-bead 11 immediately in front of the adjoining stile of the upper sash, and in order that the plate itself may be disposed a slight distance away from the stile, for the purpose hereinafter explained, said plate is offset on a line with the attaching-flange'to form a shoulder lah, which may bear lightly against the stile of the windownsash. Cooperating with this plate 14: on the partingbead is a similar plate 15, attached to near the inner edge of the adj o-ining stile of the upper sash so as to overlap said plate 14k and slide thereover as this sash is moved up and down, and so that the plate 15 may properly overlap the plate 14 said plate 15 slots 17 a may be, and preferably are, slightly shorter than the slots 17, for the purpose hereinafter explained. j

Firmly secured upon the upper rail 10a of the lower window-sash 10, so as to properly engage the registering holes in the plates 14 and 15, is a spring-catch 18, pivoted in a suitable housing 19, the inner or hook-end of said catch riding over Vthe plate 15 carried by the upper sash when either sash is opened. The outer or operating-end of the catch projects beyond the front of the housing, and for convenience in manipulating the catch said housing is provided with a projection or finger-hold 19a. The catch is actuated toengage the holes or slots in the plates by means of a spring 20, suitably supported within the housing, and to provide for a slight bodily movement of said catch laterally a slot 21 is formed therein to receive the pivot-pin 22 projecting from the housing.

By disposing the plates 14 and 15 a short distance away from the stile of the upper sash the hook-end of the catch will pass entirely through the registering holes or slots in said plates and slightly beyond the inner plate 14, thereby insuring a positive and secure engagement, and in order to insure this disposition of the plates in attaching them to the window the plate 14 is provided with the bearing-shoulder 141D hereinbefore described. Of cou-rse the shoulder may be dispensed with, and an ordinary angle-plate used and attached to the partingbead a slight distance away from the stile of the upper sash, but it will be readily understood by providing the shoulder it will prevent the plate from being carelessly placed too near the stile. It will also be noted that by providing the lip at the lower end of the outer plate it will serve to protect the hook-end of the catch from being operated by a knife-blade inserted between the meeting-rails of the window-sashes.

In applying the window locking devices the plates 14 and 15 are nailed or otherwise attached to the parting-bead 11 and upper sash 9, respectively, in such position that when both sashes are closed the holes or slots in the plates will register and the lowermost registering holes or slots will be on a line with the spring-catch for engagement of the latter therewith to lock the sashes in such closed position, the said catch being secured upon the top rail of the lower sash for this purpose. When it is desired to raise the lower sash and lock it open a slight distance the vspring-catch is first disengaged from the lowermost holes or slots in the plates, and as the sash is raised said catch when released will ride over the plate 15 and automatically engage the registering holes or slots 16, 17, immediately above, thereby securely locking the lower sash in this slightly raised position, as well as locking the upper sash in closed position. Vhen it is desired to further raise the lower sash the catch is disengaged from the last mentioned holes or slots and as said sash is pushed up the catch when released will ride over the plate 15 at one side of the holes 17a (see Fig. 3), so as not to automatically engage in said holes. But to engage the catch with any one of the upper holes 17a, and thereby lock the sash in either the position shown in dotted lines Fig. 1, or ata greater elevation, said catch is moved bodily laterally on its pivot by pushing rearward on said catch unt-il the hook-end thereof enters the hole 17 a, and, as will be noted, this bodily movement is facilitated by disposing the slot 21 at an obtuse angle with respect to the handle 18. In like manner the upper is, in operating the lower sash, the plates are stationary; but of course the lower sash may be raised and the upper sash lowered, to ventilate from top and bottom of the window', and both sashes locked securely in such position.

It will be noted that the catch has both a pivotal movement andl a bodily movement, and that the spring acts to position said catch so that the hook-end thereof will normally ride over the plate 15 at one side of the holes 17a, the holes 17 being longer or in the path of the catch in its normal position, By this arrangement the lower sash may be raised and lowered above a. certain point without being automatically locked, and this is a convenience inasmuch as the height of the catch in such instance would require the operator to mount on a step-ladder or a chair in order to reach it, and therefore this may be done only when it is desired to lock the upper sash by means of one of the holes 17 a.

Having thus described my invention, I claim:

1. In a window locking device for the vpurposes set forth, the combination with a window-frame and sashes slidable therein, the window-frame having the usual partingbead, of companion plates attached to the parting-bead and adjoining' stile of the upper sash, respectively, to slide one over the other, saidV plates having holes which register with each other, and the upper set of holes in the outer plate being out of line with the lower set of holes therein; and a springcatch pivoted upon the lower sash to engage the registering holes and have a bodily movement laterally, substantially as shown and described.

2. In a window locking device for the purposes set forth, the combination with ay window-frame and sashes slidable therein,

the window-frarne having the usual partingbead, of a plate having a longitudinal flange at one edge for attaching the plate to the parting-bead and a longitudinal shoulder on a line with the flange to dispose the plate a short distance away from the adjoining stile of the upper sash, said plate having a vertical series of holes; a companion plate having an angular flange at one edge by which it is attached to the inner edge of the stile of the upper sash to overlap the other plate, said last mentioned plate having a lip at its lower end and a series of holes adapted to register with the holes in the first men tioned plate, the upper set of holes being out of vertical line with the lower set of holes; and a spring-catch pivoted on the lower sash to ride over the outer plate and engage the holes therein, said catch having a slot through which the pivot-pin passes, substantially as shown and described.

In testimony whereof I aiiix my signature in presence of two witnesses.

JAMES E. MILLER.
